Product Description:

The MAC112C-1-KD-4-C/130-A-1/DI520LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The unit is intended for analog drive systems where closed-loop torque and speed control are required in industrial automation cells. It converts drive controller commands into mechanical rotation for positioning, conveying, or process equipment. In typical service, it is used on axes that need repeatable motion and stable speed regulation under changing loads. Its construction follows the 112 frame class of the series and includes provisions for surface-mounted blower cooling in continuous-duty operation.

Within the 112 frame, the rotor and stator are matched to winding code KD. The motor has length code C, which provides an extended active stack for higher continuous output. A 45 Nm blocking brake is fitted as standard so stationary loads remain secured when power is removed. The brake also helps hold parked loads without relying only on drive torque. Heat generated during operation is removed by axial surface cooling assisted by an AC 230 V blower mounted at the rear. The flange has a 130 mm centering diameter for alignment to gearboxes or machine beds, and the shaft reaches a nominal 1500 rpm when driven by appropriate analog amplifiers.

Signal integration is handled through an incremental encoder with shock-damped mounting, and the motor can also provide tacho feedback for incremental or absolute evaluation as required by the drive. This feedback arrangement lets the paired controller monitor shaft motion continuously during operation. The shaft transmits torque through a DIN 6885 keyway, and power is routed through a connector on side A to simplify cabinet wiring. Tachogenerator output is 3 V/1000 rpm, and the tacho is produced in standard quality for compatibility with analog velocity loops.
